HUB nnmooitrunn DOUBLE'DI-SK I To all whom may concern:

Be it'known that I,'W1LLIAM Emsrns' WILLIAMS, a citizen of the United States, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Hub Demountable Doubl Disk Wheels, of which the following is a specification.

The object of the invention is to very strong, light, inexpensive'disk wheels for. automobiles so.- constructed as to be readily demounted at the hub. Reference will 'be had to the accompanying drawing'in which Figure Iis a front ele- Figure 2' is a transverse sectional elevation on a larger scale than that of Figure 1.

Figure '3 is fastening shown in of Figure 1.

Figure 4 is an enlarged'detailed sectionalview at the connection of the hub,

parts only, 5 is a sectional-detail of a piece of showing the hub.v

In the drawing 1 indicates the ordinary hub, ,here shown as the; ream hub in an ordinary automobile wheel and 2 indicates the brake drum, This ,brake drum 2 is secured by a series of bolts 3 to a flange 4 on the hub. The hub has peripheral, outwardly, in-

of the wheel is "here shown as'beingmade of two disks'jof metal, the rear disk being'in dicated by 7 and the front disk by 8., =.'I-he front disk is shown havingmoncentric cor-"' rugations 9 which add .to the appearance and to the local stiflness against indentation from accidental causes and further'give a slight degree of elasticity in the rotativeactlon disks 7 and 8 an angular cal flange 11.

face ofth'e flange 11 of the angular ring and s turned over on. the inside of the said flange 11 as is indicated by 14, thus locking the inner edge or the disk 8 to the angular I ring. addition to this locking feature'of' the turned over edge of the aperture of the disk 8, secure the disk 8 to this flange 11 i 1 by, a. series of--'rivet s"15. To better grip the inner aperture, where the disk is turned over into the flang e' 14, furnishes'the bearin surface17, (see igure-4), -which rests directly upon theinclined bearing surface 5,

of the ring 16 is also beveled to fit t e bearing surface 5 as is indicated by 18.

The inner edge of the disk around the The outer margin'of thering 16 is made a gentle swell or outwardly extending bulge 19 of the'disk 8, thus disk, as it were, on the ed e 20 of this ring 16, the purpose being to cross section of the disks 7 and 8 as possible A series of studs 21am threaded into-the shouldering the '80 rnish as large a limitsjof diameter around thehub'whereat the-load strains are carried,

, The 7 and 8 in each other at the rim and are prpvided with re 'stering flanges 24 and 25 on the margins o 8ina of the main portion 8 of series of rivets 27. Thus tion, the flanges 10, m y mounted by means of the studs'21.:=

whereby mounting. and demounting are iacilit'ated. g

- The arrangement of the two. disks connected together in the hub region and at their margins ma be used with a varlety of rims but ll 'pre er to use it with the type of rim here shown in which the arrangement of the parts makes a ver desirable whee1c0n struction, in that the skid shocks on the disks are taken up by the two disks being well braced against each other at thehub juncture and well connectetl together at the rim making the well known triangular strain lines so essential in w an economical design of braced structures.

The type of rim here shown is one wherein the side ring is a removable ring or flange i indicated by having the tread seat 31, 20

which rests under the bead of the tire, the latter being shown in dotted lines in Fig ure 2; p A series of studs 32 having elongated heads 33, which approximate the old door button in appearance, are screwed into special nuts 34 on the inside of the flange 26 ofthe main rim. These studs 32 are I screwed home with the heads 33 against the flange 26 before the tire is inflated and are arranged to fit-tightly against this flange when the heads are approximately radial with respect to the wheel.

- 'The detachable ring 30 Fig.1, and provided, on opposite sides of the cut, with blocks 36 having projections 37 which 'engage undercut portions of the flange '26 and rim 28 and, hold the ring 30 against radial displacement. However, the flange 31 of the sidering, resting under the bead of the tire is held in place by the tire pressure so that the chief function of the blocks 36 is to register theends of the ring I at 35 centrally on to the head of the special stud 38, so that at all times the ring 30 may bem'ade to have its ends held by thesame head 33 and prevent the careless operator from placing the ring 30 on to the rim with the open ends between the studs instead of directlynnderneath the head of the stud.

In the side of the ring 30 l emboss projections 39 which project outward on each side of the'inner end of the elongated heads 33 of the studs 32 to act as detents or registering points to prevent the revolution of the studs when the tire is inflated. The

smallest amount of inflation will make a side pressure on the ring 30 that. will hold these projections 39 so' tightly in contact on each side of the heads 33 of the studs that it will be practically impossible to turn the studs. But when the tire is deflated the ring 30 may be pressed inward slightly so as to permit the turning of these heads 33, degrees as is shown by aposition at) in Figure 1. a f

is divided at 35,

32, 90' degrees with the tire deflated, the ring 30 is easily removed and the tire changed with a mmimum amount of trouble. Claims: S
